Streaming multimedia content with UDP has become increasingly popular over distributed systems such as the Internet. However; because UDP does not possess any congestion-control mechanism and most best-effort trafic is served by the congestion-controlled TCP, UDP flows steal bandwidth from TCP to the point that TCPjows can starve for network .resources. Furthermore, such applications may cause the Internet infrastructure to eventually suffer from congestion collapse because UDP trafic does not

... elfregulate itself: To address this problem, next-generation Internet routers will implement active queue-management schemes to punish malicious trafic, e.g., non-adaptive UDP j o w s , and to the improve the performance of congestioncontrolled tra$fic, e.g., TCP flows. The arrival of such routers will cripple the pe formance of today 's UDP-based multimedia applications. So, in this papel; we introduce the notion of inter-packet spacing with control feedback to enable these UDP-based applications to perform well in the next-generation Inter-net while being adaptive and self-regulating. When conipared with traditional UDP-based niultirizedia streaming, we illustrate that our counterintuitive, interpacket-spacing scheme with control feedback can reduce packet loss by 90% without adversely affecting delivered throughput.
